FLAME ARRESTERS

Flame arresters are devices that protect against explosions by preventing the transmission of flame and explosion in machines, equipment, and plants.  These autonomous safety systems limit the effects of the explosions, rendering them harmless. They are intended to allow flow but prevent flame transmission.

DEFLAGRATION

A deflagration is an explosive combustion process in which the flames propagate at subsonic velocity. For deflagration, there are end-of-line and in-line deflagration flame arresters. When installing in-line flame arresters, it is imperative to adhere to the ignition source's maximum distance (L).

DETONATION

A detonation is an explosion propagating at supersonic velocity characterized by a shock wave. Detonations occur in pipelines with long distances to the ignition source (L > 50 x DN being an example for explosion group IIA).

An in-line detonation flame arrester's flame arresting capability and mechanical strength are much more significant than an in-line deflagration flame arrester. Devices designed for detonation conditions will provide deflagration protection as well.

STABILIZED BURNING

Stabilized burning is the steady burning of a flame at or on a flame arrester element. Survival of such conditions requires the selection of an arrester model designed for endurance conditions.
